The Open Data Day is a project of the Open Knowledge Foundation (OKFN), with events all over the world that will happen between March 2th and 8th. It is an annual celebration of open data all over the world and it is a great chance to talk about Common Voice to an interested audience.
Right now there are 185 events, but often more appear in the days before the date, so it’s worth to check this website again once in a while:
